Good question. That was the old BSD behaviour, but was later changed
by some reason I don't know. It would be the for sure simplest
solution (adding one line of code).
RFC826 suggests that new arp requests should be sent before the
old arp entry is deleted, therefore I gave this as an example
of a solution to the problem. Which solution does not matter to
me, only that the problem must be solved.
